Hi there pinnacleentmgmt,
Thanks for joining us and being a part of the QuickBooks family! From your question, it sounds like you're also using QuickBooks Payments, which is a great for accepting customer payments online using credit card.
When it comes to refunding a credit card payment made through QuickBooks Payments, there are a few steps to follow. I have an article that outlines the steps you need to take: Refund a credit card payment
If you'd like to take the extra step of making sure it was processed in the back end, feel free to give the Payments team a call at 1-833-317-2226 from Monday to Friday between 9 a.m. and 8 p.m. ET. An agent can even help walk you through the steps if you'd like!
That should get you on your way. Take care and have a wonderful week. :)
